In projective geometry, any pair of lines<span> always intersects at some point, but </span>parallel lines do not intersect<span> in the real plane. The </span>line<span> at infinity is added to the real plane. ... In the projective plane, the two opposite directions of a </span>line<span> meet each other at a point on the </span>line<span> at infinity.
Using the formula ending amount is 1649=a p=initial amount=100 t=10 r=r
so 1649=100e^{10r} divide both sides by 100 16.49=e^{10r} take ln of both sides ln(16.49)=10r divide both sides by 10 (ln(16.49))/10=r use calculator 0.28027=r about 28% interest
